What has the Conservative Party conserved, in recent memory? Does it even acknowledge that its name should also be a job description? How much – if any – of its instinct for preserving the traditional, the venerable and the beautiful does it retain?

How many of them, in their inner hearts, still subscribe to the axiom that when it is not necessary to change, it is necessary not to change?
